R.clinophylla breeding

Georg,

What a clever, easy way to air layer and there is no digging or transplant shock later. Easier than making cuttings!

THANK YOU,

Jim

Hi Jim P.

Yes, it works great…it’s too easy. This particular application (or very very similar technique) of air layering was also mentioned by another contributor on this forum, who also has had great results with it…just out of coincidence, I am pretty sure it was one of the other Ozzies who contributes here LOL!!!

I must have missed it. Love those Ozzies!

Sweet!

UPDATE

I couldn’t resist, so I continued to add pollens to clinophylla and clinophyllaXbracteata, even though I suppose such young plants could not really be expeted to want to bear “fruits” readily??

I used pollen mainly from Crepuscule, and lesser attempts were made using Flower Carpet Scarlet pollen ------>100% failure, so far (~30-40 attempts).

It has been a fun project to fiddle with, in any case.

Also, the clinophylla plant is way less floriferous compared to its clinophylla X bracteata “cousin”.

For fun, I am starting to use their pollens now on one diploid seedling (seed from USA), which germianted by embryo culture, one of only two to have survived a near total fungus gnat infestation. I don’t expect takes, however one cannot ever be 100% sure of these things, so why not try even on the maiden flower of a seedling LOL!!!

This is totally crazy fun!

Speaking of the Clinophylla X Bracteata, the “runt” one I have grown for some time is taking off like a shot. There are two, perhaps three tip rooted pieces which appear to be WELL rooted. If anyone is interested in them, please let me know. I’m going to have to remove them from the pot they chose, which, ironically, is Minutifolia. Kim

Some weeks ago now, I threaded one cane from clinophylla and one from clinoXbracteata through the holes of plastic pots, and then covered these with dirt to air layer them (I never wound the stems when doing this trick).

LOL…now, quite a few weeks later, both the clino and the clinoXbracteata stems have grown roots out of the pot holes, causing their pots to anchor to the ground!!! Very aggressive rooting!!!

I released both yesterday as new plants…this extra back up thing is prolly a waste of time, as I can’t see the parent plants die on me, they are thriving here. “Happy as Larry!!”

I am totally not happy about the hooked thorns. I just removed about 7 pointy bits left of them which had hooked into my fingers/palms after clearing under these bushes a few hours ago.

Since this has happened, I am now going to give this species/species cross the flick, as well as all my other roses with nasty thorns. I am totally over that aspect of roses!!!

Welcome to the club, George! LOL! You would have laughed yourself silly listening to Ralph after I asked him if we could breed a thornless moss rose! Kim

Hmmm… the clino & clinobracteata plants are in heaven… its just too bad!

Kim, it would have been nice to be a fly on the wall to listen in on that particular “greenhouse discussion”…is it possible to breed thornless mosses???

I think it would be a mistake to give up on clinphylla projects. I hate bracteata so you may want to ask someone that actually likes it :stuck_out_tongue:

Rose Gilardi would not have been Rose Gilardi had it been thornless. Shadow Dancer would not have been Shadow Dancer had it had thorns like its close relation, Rose Gilardi – put it that way (the answer is likely no).

I’ll take on clino again when a thornless one becomes avail. Them thorns were vicious hooks.

The references say theyre not hooked like bract. though, no?

Yes, the “Clinophylla” seedling I had here as well as the clinophylla X bracteata seedling both were armed with small hooked thorns.

Bummer.

George,

Now you understand why I hate prickles. It seems to come with many rosarians over time and after too many occasions being pricked. One summer I grew a crop of warts on my hands and I had only ever had one 40 years before. I am sure all the pricks in my skin enabled the virus to penetrate and grow. It took a long while to eliminate them, even after having them burned off.

Jim

PS- I notice they often “go for the joints” on my fingers and are harder to extricate there. Always worry about gettng an infection in a joint.

Hope things went well with your dog.

Hi Jim P!

I am so sorry to hear about that wart problem, how horrible for you!! I am sooo glad you actually managed to rid yourself of it, it is not easy.

Pooch is better, survived the op…minus one toe, and minus a few small “bits and pieces”, but he is one gazillion times happier, and there is no more pain!!! Thank you sooo much for caring to ask!!

:0)

Michael, I also looked through the clippings in the bin…just to give you a more detailed description of these prickers. The prickers were slightly curved in the more mature wood, not really curved on the very young wood. They were also placed at small angle to the stem, which added to the “catching” propensity. I do not have a young R.bracteata specimen to compare its prickers with these…best I can do.

In real life, these 2 bushes had a whispy octopus-like character about their growth /architecture, which caused immediate hooking as you came near them and the wind blew their parts onto you, let alone worked close to them.

BTW, I still have numerous R.clinophylla seed in warm stratification…it is most unlikely that any of these may show a thornless mutation, however I am going to watch out for this in any of the seedlings that do pop up! Why not!!!

“…I think it would be a mistake to give up on clinophylla projects…”

LOL… many months after pulling out my remaining Clinophylla due to my hatred of it being a prickly tangled mess of a plant, I just noticed a substantial new plant has emerged from the original roots that remained, it kinda looks several months old…have been too busy lately to even look at the garden, such is life.

Clinophylla sure is one tough plant!!!

As this seedling originated from OP seed that came all the way from India, I think it is now really telling me something… ummmmm… so I dug it out of the ground and put it in a pot and will take care of it, to get flowers again…maybe, just maybe, I’ll try breeding with it again, this time using it as pollen parent.

I have no doubt this thing will take root real fast, and start growing out even in a few weeks, our winter here is so warm by North American standards, it is laughable.

:astonished:)
